The invention relates to a connection device () for use in the negative pressure therapy of wounds, comprising a flexible conducting means () and a connecting body () made of an elastomeric flexible material which can be applied to a negative pressure dressing which covers the wound and seals the wound off from the atmosphere, wherein the connecting body () has a centrally arranged raised first area () which receives the conducting means (), and a flatter flange-shaped second area () opposite the first area, which second area forms a contact plane () on the negative pressure dressing, wherein a conducting portion () which is closed on all sides and is formed by the central first area adjoins a free end of the delivery lumen () of the conducting means () which opens in the central first area, wherein said conducting portion first opens at a distal end into an interior () of the central first area () and from there is in fluid communication with the suction lumen () of the conducting means (), characterized in that the central first area () has one single contiguous opening () which opens towards the negative pressure dressing in the contact plane (), such that the at least one suction lumen () communicates with the wound space through said contiguous opening (), and that extensions () integral with the first area () and extending in the contact plane () with free ends protrude into said contiguous opening () and form a means for preventing penetration of dressing or wound inlay materials sucked out of the wound space.

Vacuum generating device

An attachment device () for use in the vacuum therapy of wounds has a vacuum-tight mounting element (). A conduit is fastening to the upper side of that mounting element in a vacuum-tight manner. The conduit () communicates with the wound space through openings () in the mounting element () and in the vacuum dressing. The conduit () is flexible and flat and is connected to the mounting element () non-detachably and extensively in a longitudinal section () on the wound side over at least 70% of its surface projected perpendicularly onto the mounting means (). The conduit () is made out of a flexible elastomer material of Shore A hardness of no more than 60 and the thickness (D) of the combined conduit () and mounting element () is no more than 7 mm.

Attachment device for use in the vacuum therapy of wounds

An apparatus () for carrying on the body of a user to generate a vacuum for medical applications, in particular, for the vacuum therapy of wounds on the human or animal body, has a vacuum-producing device and a vessel () that is disposable after use for receiving body fluids, in particular, wound exudates suctioned out of a wound, and with a connection () for a suction tube leading to the body for this purpose, wherein the vacuum-producing device is disposed in or on a first housing part () of the apparatus and the vessel () forms a second housing part () of the apparatus or is disposed in or on the second housing part (), and the housing parts () are separably fixed one against the other. The apparatus () has fastening means so that it can be worn and carried on the body of the user. The device is characterized in that the first housing part () is provided facing away from the body when the apparatus is carried on the body of the user (mobile operation) and the second housing part () is facing the body with both housing parts () being essentially disk-shaped and lying one against the other in an essentially vertically oriented separation plane ().

Device suitable for carrying on the body of a user to generate vacuum for medical applications

A device for carrying on the body of a user to generate a vacuum for medical applications, having a vacuum-producing device and a disposable vessel, with a suction tube connection leading to Ihe body, wherein the vacuum-producing device is disposed in a first housing part of the device and the vessel forms a second housing part of the device, and the housing parts are separably fixed one against the other, the device having body fastening means. The housing pans can be separably fixed to each other by a positive-action locking mechanisms and the locking mechanism having a manually operable operating element. The first and/or second housing part is constituted for manual gripping so that the device or the first or second housing part can be gripped and separated from the other housing part, and the manually operable operating element is provided in the region of the manual gripping.

A portable device () to generate a vacuum for the medical treatment of wounds on the bodies of humans or animals has a vacuum-producing suction pump () in a first housing part () of the device and a vessel () for receiving body liquids. Vacuum is applied for vacuum communication between the suction pump (), the vessel () and a suction tube () leading to the body. A pressure sensor () measures the pressure in a tube section () and a programmable electronic control unit () controls the suction pump () in dependence on pressure values measured by the pressure sensor (). The electronic control unit () deactivates the suction pump () if a rate of change in pressure (&#x394;p/&#x394;t) detected by the pressure sensor () exceeds a defined threshold value toward decreasing vacuum.

Vacuum generation device for vacuum treatment of wounds

Medical compresses, especially gauze compresses, are proposed which can be especially advantageously folded and stacked.
